When creating a new ticket, one can set a value for the SLA.
It appears these values are configured in the file /opt/rt4/etc/RT_SiteConfig.d/sla.pm
However, editing this configuration (i.e. adding a new SLA value to be selected) does not seem to add the new option as expected (i.e. the new value does not show up as an option in the SLA selection dropdown).
Am I editing the wrong file or do I need to run a command to have my changes take effect?
